METHOD FOR PRODUCING CALCIUM CARBONATE SOLIDS FROM ALKALINE MINERALS
The present disclosure relates to a method for producing calcium carbonate solids from alkaline minerals including the following method steps: Supplying alkaline minerals and an extraction agent into a reactor tank. Stirring the alkaline minerals and the extraction agent in the reactor tank such that a first suspension is formed. Draining of the first suspension from the reactor tank and separating a liquid phase comprising calcium from the first suspension and transferring the liquid phase into a carbonation tank. Supplying a gas comprising CO2 into the carbonation tank, wherein the consumption of CO2 results in the precipitation of calcium carbonate solids thereby generating a second suspension and nucleating and growing of the calcium carbonate solids. Furthermore, a measure of the consumed CO2 is determined by at least one sensor.
